STATIC-ELECTRICITY DISSIPATOR FOR PAPER WEBS OR SHEETS.

To all whom it may concern:

Be it known that I, HOWARD M. BARBER,

a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Static- Electricity Dissipators for Paper Webs or Sheets, of which the following is a specification.

My invention relates to improvements in static electricity dissipators for paper webs or sheets and is directed to that type of dissipator or neutralizer in which electricity is removed from the web by slightly moistening the same, also providing a static discharge through a moistened wick contact.

The object of my invention is to provide mechanically operated means, such as a governor, for bringing the web and dissipator into and out of co-action, said means being under the control of the speed of the press whereby the dissipator and web are brought into coaction automatically when the web is running and out of coaction when the web is still.

This invention is directed more particularly to mechanically operated means as above set forth for moving the dissipator into and out of contact with the web as distinguished from my co-pending application filed of even date herewith, Serial No. 765,313 which is directed more particularly to the means for moving the Web into and out of contact with the dissipator.

If the moistening wick of the dissipator be left in contact with the web when the web is still, it will saturate the paper to such a degree as to materially weaken or break it. This invention is directed to means for avoiding this trouble.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents in side elevation so much of a folding machine as will give a clear understanding of the construction, location and operation of the several parts of my improved static electricity dissipator, the parts being shown in full lines in their position when the web is running and in dotted lines in their position when the web is still, and Fig. 2 is a transverse vertical section taken in the plane of the line A-A of Fig. 1.

Specification of Letters Patent.

Applicationfiled May 3,

Patented May 16, 1916. 1913. Serial No. 765,312.

The web 2 is shown as passing around a series of rolls 3, 4, 5, on its way from the printing press, not shown, to the former 6 of the folding machine. The moistening wick is denoted by 7 and its fountain by 8, which fountain is provided with end trunnions 9 mounted to rock in suitable bearings 10 in the main frame 11. Liquid is supplied from a stationary reservoir 12 mounted on a bracket 13 of the main frame, through a feed pipe 14: having an axially arranged branch 15 leading through one of the trunnions 9 into the fountain 8. The feed pipe 14 is provided with a suitable cook 16.

The fountain 8 is rocked by mechanically operated means under the control of the web to bring the moistening wick 7 into and out of contact with the web. The mechanically operated means is herein shown as a governor 17, the movable element 18 of which is connected to the arm 19 of alever pivoted at 20 and the other arm 21 of which lever is connected by a rod 22 to an arm 23 of a lever pivoted at 24., the other arm 25 of which lastnamed lever is connected to an arm 26 fixed to move with the fountain 8. An adjustable counterbalance weight 27 is provided on the arm 21 of the lever 19, 21, for assisting in holding the parts in their normal position with the moistening wick out of contact with the web 2. The governor 17 is herein shown as operated through a train of gears 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, driven by any suitable means, not shown, from the press. A ground wire 38 connects to the fountain 8.

In operation, when the press and thereby the web is still, the moistening wick 7 is held normally out of contact with the web. WVhen the press and thereby the web 2 is running, the governor 17 rocks the fountain 8 to bring the wick into contact with the web. The governor may be so adjusted that when the speed of the press reaches a predetermined point the wick is automatically brought into engagement with the web and when the press slows down to a predetermined point the wick is automatically moved out of contact with the web.

It is obvious that the particular mechanically operated means shown herein for automatically bringing the web and dissipator into and out of coaction, is only one of many different forms which might be shown for accomplishing this result, hence I do not wish to limit myself to the particular means herein shown and described.

While I have shown this invention in connection with running Webs, it is to be understood that I include sheets as Well.

What I claim is 1. A static electricity dissipator for Webs including a moistener and mechanically operated means controlled by the speed of the press for automatically bringing the moistener and Web into and out of contact.

2. A static electricity dissipator for Webs comprising a moistener and mechanically operated means controlled by the speed of the press for automatically bringing the moistener into and out of contact With the Web.

3. A static electricity dissipator for Webs comprising a moistener normally out of contact with the Web and mechanically operated means controlled by the speed of the press for automatically bringing the moistenor and Web into contact.

4. A static electricity dissipator for Webs comprising a moistener and mechanically operated means controlled by the speed of the press for automatically bringing the moistener into contact With the Web When the Web is running and out of contact with the Web when the Web is still.

5. A static electricity dissipator forawebs comprising a fountain, a moistening Wick carried thereby, a mechanically operated device controlled by the speed of the press for rocking the fountain to move the Wick away from the Web When the Web is still and for rocking the fountain to move the Wick into contact With the Web When the Web is running.

In testimony, that I claim the foregoing as my invention I have signed my name in presence of two Witnesses, this twentyfourth day of April, 1913.
